The DC voltage measured across pins 17 and 18 is proportional
to the laser bias current. Use the equation:
Use this output to monitor laser performance and EOL condi-
tions. A schematic and typical behaviour are shown in Figures 3
and 4. I
tion is not required.

The DC voltage that can be measured across pins 19 and 20 is
proportional to the laser monitor diode current through a 200
resistor in its path. This output remains constant and can be
used to monitor correct operation of laser control circuitry,
a deviation indicates faulty behaviour. A schematic and typical
behaviour are shown in Figures 5 and 6. V
range of 0.01 and 0.2 Volts. Leave pins unconnected if feature is
not required.
